Some gases are responsible for heating of atmosphere (green house effect). Identify from the following the gaseous species which does not cause it.

Answer: (D)

Solution

Greenhouse gases absorb and emit infrared radiation, contributing to the greenhouse effect and global warming. Common greenhouse gases include

CH_{4}

(methane),

O_{3}

(ozone in the troposphere),

H_{2} O

(water vapor), and

CO_{2}

.

Nitrogen (

N_{2}

) is a diatomic molecule that does not absorb infrared radiation effectively and therefore does not contribute to the greenhouse effect.
